BACKGROUND OF THE INVENTION

1. Field of the Invention

The subject invention entails a wind-propelled vertical turbine device that drives a power generator and a ventilator, or any heat dissipation device.

2. Descriptions of the Prior Related Arts

The conventional roof ventilator is a kind of miniature windmill. When wind blows onto the blades the blades are rotated to exhaust hot air to outdoors. The ventilator typically does not incorporate the function of power generation. Even if the conventional ventilator was to be equipped with a generator, the typical ventilator blades have relatively small wind-catching area that the wind-powered torsion can hardly feed the power generator. Therefore, it is difficult for the conventional ventilator to provide additional power-generation function.

SUMMARY OF THE INVENTION

It is the objectives of the subject invention to design a ventilator that will provide both power generation and ventilation through utilizing the most abundant and renewable wind energy.

To achieve the above objectives, the subject invention incorporates three hardware components, namely, the vertical, multiple-blade wind turbines, a ventilator, and a power generator. All three components are inter-connected as an integral assembly that can provide ventilation function while generating electrical power.

The purposes of the subject invention can be best achieved by installing the subject invention in the region with abundant wind flow.

Through catching the wind energy the wind turbines will rotate and a significant torsion is created to concurrently drive the power generator and cause the ventilation blades to rotate to create outward airflow.

The wind turbine component is a vertical, multiple-blade assembly designed to effectively catch wind energy. The size of the blades are enlarged and properly angled to maximize the catching of wind volume.

The power generator assembly incorporates a coil winding on top, a shaft, and a bottom tray. The coil winding interacts with the magnet assembly on top of the ventilator housing for generating power.

The ventilator consists of a disc-like magnet assembly with multiple vertical blades and a rotary tray at bottom fitted on the shaft of the power generator via a bearing. The disc-like magnet assembly and the rotary tray are assembled on top and bottom to provide a middle housing surrounded with vertical ventilation blades in the cylindrical body. The shaft protrudes from the center of upper end of the disc-like magnet assembly to connect with the wind turbine assembly, thereby to get connected with and driven by the wind turbines.

In order to increase hot air exhaustion efficiency there are multiple circulation acceleration blades placed on the rotary tray of the ventilator to help speed up exhausting/ventilating process, whereby the hot air can be quickly exhausted through the turning of ventilating blades.

The subject invention can be further explained through the following descriptions and accompanying drawings, wherein:

DETAILED DESCRIPTIONS OF PREFERRED EMBODIMENTS

The subject invention is illustrated through the following two preferred embodiments.

First Embodiment

The First Embodiment of the subject invention is shown from FIG. 1 through FIG. 5.

The subject invention comprises three major elements: a wind catching device 1, a ventilating device 2, and a power generating device 3.

The wind-catching device 1 is composed of multiple wind turbines 10, or blades, each connected with supporting frames 12 at the top and bottom, which are connected to the shaft 30 via two bearings 120, 121. The shaft 30 is further connected to the ventilator 2 and power generator 3.

The ventilator device 2 is composed of a disk-like magnet assembly 20 on top, a rotary tray 22 at bottom, and multiple vertical blades 21 in between for ventilation, which form a cylindrical structure with air chamber 210 in the middle.

A sleeve 200 protrudes from the center of upper end of the disc-like magnet assembly 20 to connect with the bearing 121 and the supporting frame 12 of the wind turbines 10, whereby the sleeve 200 can be driven by the wind turbines 10 to rotate.

In addition, there are multiple circulation acceleration blades 23 right above the rotary tray 22, connected to a bearing 24, and ultimately connected to the vertical axis 30 to be integrated with the power generation device 3.

The power generation device 3 is composed of a coil winding assembly 31 on top, a circular bottom tray 32, and the shaft 30 in between. The bottom tray 32 is to be fixedly mounted on top of roof opening 5. The coil winding assembly 31 is to be snugly placed on top within the ventilator housing 210 to cause induction between the coil winding 31 and the disk-like magnet assembly 20 to generate power.

The shaft 30 from power generator protrudes upward to connect with the two bearing plates 120, 121 to be engaged with and driven by the wind turbines 10, thus forming the integral assembly of the subject invention to provide the duel function of power generation and ventilation when mounted at the roof opening.

Please refer to FIG. 5, when the wind-catching turbines 10 rotate to cause the shaft 30 to turn, the disk-like magnetic assembly 20 is driven to turn around the coil winding assembly 31 to generate electricity. Meanwhile, the hot air B is gathered at the underside of roof and will pass through the roof opening A into the ventilator housing 210, further pushed by the circulation acceleration blades 23, through the openings between vertical blades to exit the building. Thus the room temperature can be reduced.

Second Embodiment

The Second embodiment of the subject invention is shown from FIG. 6 through FIG. 8.

The second embodiment of the subject invention, the Vertical Wind Turbine Generator with Ventilator, includes a wind turbine assembly 1 a, a ventilator 2 a and a power generator 3 a, which is the same as the first embodiment. In the second embodiment, the wind turbines 1 b of the wind turbine assembly 1 a are respectively connected to the disc-like magnet assembly 2 b and the rotary tray 2 c of the ventilator 2 a via supports 1 c.

When the wind turbines 1 b, connected to the ventilator unit 2 a, are blown by wind to slowly rotate, the disc-like magnet assembly 2 b of the ventilator 2 a rotates around the power generator coil winding assembly 3 c, fitted on the shaft 3 b, to generate power output C. In addition, due to thermal circulation, hot air B in the room gathers and ascends toward the ceiling and passes through a raised barrel 4 a, which is connected to the opening A on the roof. Then the hot air enters the hollow space 2 e defined by the exhaustion blades 2 d of the ventilator 2 a. The circulation acceleration blades 2 f of the rotary tray 2 c then drive the hot air to pass through the exhaustion blades 2 d to exit the room. Consequently, while generating power the room temperature is also lowered.
